If youre researching top of the line regulators, you have to consider ScubaPro and this is their best. It reminds me of their 2nd stage regulators from the late 80s with all the chrome. Its very light and well built. A huge step up from mid-grade regulators, its the easiest breathing regulator Ive owned and Ive been diving for over 20 years. Scuba.com is an excellent company - the best online store as far as Im concerned. You get manufacturers warranties and no gray-market products like LeisurePro sells.

Its top of the line. You wouldnt even know your under water if you had your eyes closed. Breathes with such ease. A700 is worth the extra.

Questions and Answers

Questions and Answers for
ScubaPro MK25 / A700 Regulator System:

Marc:

Im wondering which regulator to buy the scuba pro mk25a600 or the a700?

Bill(Certified Scuba Instructor at Scuba.com):

The A700 is the top of the line for Scubapro. It is a metal second stage so works well for any diving conditions, including cold or ice environment. The S600 has been one of their top sellers and ranks as one of the best performing regulators. The second stage will be lighter than the A700.

Lili:

Which is better between the Scubapro mk25/S600 or Scubapro mk25/a700 and Atomic M1?
Tks

Bob(Certified Scuba Instructor at Scuba.com):

You are asking which is better between a brand new Ferrari, Aston Martin or Lamborghini. They all are very high performance items. In this case, though, the Atomic M1 is the first regulator designed specifically for mixed gas diving of components with a very low friction rating in contact with O2. If you don't have a specific need for that sort of regulator, then I'd not go that route.

Lili:

@Mark - thanks for your answer on my previous question but if the Atomic M1 is better than the Scubapro mk25/a700 then why is the M1 cheaper?
When was the M1 first manufactured? What about the mk25, s600 or A700?
Thanks much
L

George:

Sirs:
I just purchased the ScubaPro MK25 / A700 Regulator from Scuba.com. Last weekend, I had the face of my second stage fall off a rental unit here in the Philippines, and I had a couple of big drinks of saltwater before I got over to my octo.
And other than the fact that it is quite the heaviest first stage I have ever lifted, it looks great. You can imagine how pleased I now have something with bullet-proof reliability! (I prefer that my salty drinks are Margaritas!)
My question is: do you mount the first stage (yoke-style) with the low pressure outlets up or down? The Scuba.com instructor mounted it with the low pressure ports up (which maximixes rotation), but traditionally I have mounted similar units with the low pressure ports down to make a compact profile for the unit and to avoid banging my head on it.
As this is a piston-style reg, I guess the case could be made that it is a matter of indifference - the reg delivers the same amount of air in any position. However, I would some thoughts from people more knowledgable than I.
Many thanks,
Ged Smith

Bill(Certified Scuba Instructor at Scuba.com):

Setting the hoses up on the 1st stage is personal preference. It does not effect the performance of the regulator with the ports up or down.

Colin:

Does the MK25/A700 regulator system have an advantage over the MK17/A700? If so, is it worth the price difference?
Thanks

Greg(Certified Scuba Instructor at Scuba.com):

The difference is in the first stage regulator. The ScubaPro MK25 uses an air balanced high flow piston. This regulator has a first stage swivel and only one high flow second stage port. The ScubaPro MK17 uses a balanced diaphragm. This regulator does not have a first stage swivel and two high flow second stage ports. Environmentally sealed regulators use the balanced diaphragm to create a “dry Chamber” for air regulation.

Jess:

Which is easier and better of the two: this Scubapro MK25/A700 or the Atomic M1?

Bob(Certified Scuba Instructor at Scuba.com):

Both manufacturers are well known to make top of the line, high performing scuba equipment. A diver could not go wrong with either choice.

Lili:

@Clarke - its disappointing that you did not answer my question but gave me a couple of links to look into. Again, I was advised by Your Bill to buy an Atomic M1 as opposed to the Scubapro Mk25/a700. I wanted to know why the M1 was cheaper than the mk25/a700 if it was better.
2) when did the m1 come out? When did the a700?
Thank you

Clarke(Certified Scuba Instructor at Scuba.com):

Hello Lili, Thank you for your inquiry! The M1 employs state-of-the-art metals specifically chosen for extreme diving situations. Monel parts are used internally in the first stage for high strength, corrosion-resistance and oxygen compatibility. 316 Stainless Steel, multi-layer Zirconium coated Brass, and Titanium are used throughout the second stage. The M1 valve body is Zirconium/Nickel over Brass and the seat saving orifice is Stainless Steel. The date of when the M1 arrived on scene is not stated on Atomic's web site.

Jay:

1. What is the cost if I only wanted to purchase the second stage of the MK25/A700 Regulator System?
2. Do you give keyman deals to instructors who work/teach at a SCUBA retail store that sells primarily SCUBAPRO equipment?
